NLCs were generated in vitro by culturing PBMCs from CLL patients for 10 days with/without the addition of 0.5 µM lenalidomide. Then, nonadherent cells were removed by vigorous pipetting and the remaining adherent cells were harvested for analyses. We inspected the whole-genome gene expression profiles of NLCs (control sample vs. lenalidomide-treated sample) derived from 4 CLL patients by microarray. Supervised analysis identified 584 genes differentially expressed upon lenalidomide treatment, 352 up-regulated and 232 down-regulated (p<0.05). RNA was extracted with the RNeasy Plus Mini kit (Qiagen, Valencia, CA, USA). Large-scale gene expression profiling (GEP) was performed by hybridizing RNA from NLCs treated or not with lenalidomide 0.5 µM for 10 days (n=4) on 4X44K Whole Human Genome Microarray (Agilent Technologies, Palo alto, CA). Genes were defined as differentially expressed between groups (NLCs CTRL vs. NLCs LENALIDOMIDE) at p<0.05 (paired t-test) and fold change ± 1.5 by using Gene Spring GX v12.6 (Agilent) software.
